stacktrace

Description of problem:
Actually 3 problems, only one easy to fix. dnf missing dependancies, a coredump when asking --version, and the impossibility to change the keyboard settings anymore.

Version-Release number of selected component (if applicable):
ktouch-16.12.3-1.fc26

How reproducible:
always

Steps to Reproduce:
1. install ktouch under F26 using dnf
2. start ktouch
3.

Actual results:
a blank window

Expected results:
the full app

Additional info:
Those issues might not be related, tel me if I need to create new ones.

When installing from dnf, I got several issues while starting ktouch:

file:///usr/share/ktouch/qml/TrainingScreen.qml:20:1: module "QtQuick.Controls" is not installed 
     import QtQuick.Controls 1.3 

file:///usr/share/ktouch/qml/Balloon.qml:22:1: module "QtGraphicalEffects" is not installed 
     import QtGraphicalEffects 1.0 

After manually installing the qt5-qtquickcontrols and qt5-qtgraphicaleffects packages, the application starts.

However I still have the following issues :
$ ktouch --version
ktouch 16.12.3
Segmentation fault (core dumped) see attached coredump.


Last issue, I am not able to change the default language/keyboard settings. The menu is not shown. On stdout there are few "QML Row: Binding loop detected for property" warning. I don't think it's related but looking for the documentation there should be a keyboard settings somewhere. The previous version I used was 2.3.0 under F23.
